Water demand management and conservation along the lower Orange River

Overview and Purpose

Working with a range of farmers from Noordoewer and Vioolsdrift, and the Joint Irrigation Authority (JIA) responsible for their shared irrigation scheme in this part of the lower Orange River, this project has been testing a number of different management approaches and technologies to assist in developing a water management strategy. Activities include:

  • installation of soil moisture probes, meteo station, flow meters and other telemetry equipment to provide quasi real-time data online, allowing improved irrigation scheduling
  • training sessions and study tours with farmers to irrigation schemes in other parts of the basin, to encourage water demand management and water conservation at the farm and scheme level
  • drafting a water management plan for the irrigation scheme.
